His name is Bob Lewis, of the classic 1930's paper on radial ground planes (Brown, Lewis, and Epstein). He is 83 and still continues his interest in antennas. He is currently one of the review board of Communications Quarterly. BTW, the proper configuration is an upright quarter wave element and quarter wave length radials. Since in this case the radials are tuned, they must be exactly quarter wave length. Forrest Gehrke feg@dodger.att.com k2bt
